i just thought of something, which may be how these hoods are done anyway, which is to not have a hinge under the hood panels, but like a rod/pins that is on each end of the panel and allows the hood to turn up. the hood would lift up from the side, but then would go down at the center. you could mount the pins like 1.5" from the center to allow the hood to swing up.
hope this helps.
